Hello

The following sample report <b>ZUS_SDN_BCCIIXMLT2</b> (modified from BCCIIXMLT2) shows how to upload an XML file from the application server.

If the structure of the XML is according to the structure of a DDIC structure then you can directly convert the XML into the DDIC record using the transformation ID (= identical) which is used to convert ABAP to XML and vice versa.

*
*  BCCIIXMLT2 - sample program
*
*  This sample program shows how to read an XML document from a file
*  in the appserver's file system, parse the document into a DOM
*  representation and display the content as a list.
*  Additionally the DOM representation is rendered back into an XML
*  stream and stored as an output XML file on the appserver machine.
*
*  This sample program uses ABAP strings to represent the XML input
*  and output streams. See BCCIIXMLT1 for using internal tables.

If you don't have prior XML exposure then use as suggested by Uwe
